METHOD OF SURGICAL TREATMENT OF DISTAL HYPOSPADIA IN BOYS Russian patent published in 2011 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to urology, Loose rhomb-shaped skin flap is cut out from internal leaf of foreskin. Flap is separated and preserved in physiological solution. Flap is cut out on ventral surface of penis body with further dissection of skin on it. Cut is made 2 mm deeper and is made wider by mobilisation of edges sideward, thus increasing width of uretral site. After that defect in site centre is covered with loose rhomb-shaped flap, which is thoroughly fixed to head tissue and tunica albuginea of penis body in such a way that it tightly fits with its base to wound surface, covering it with epithelial lining. Neourethra is cut out by flaps of de-epithelised foreskin obtained by dissection of preputial sac along dorsal surface to sulcus coronarius, which are moved around balanus onto ventral surface and fixed to tunica albuginea of cavernous bodies and balamus tissue in two layers, first - the right one and then the left one with an overlap. Due to the method high cosmetic result is achieved: vertically directed meatus, straight penus body, bringing of external orifice of urethra strictly onto balamus apex makes it possible to ensure anatomically and functionally correct version of the act of urination and the act of ejaculation.

EFFECT: method makes it possible to avoid development of post-operation complications, scarring of urethra with further narrowing of its lumen and disturbance of urine flow and thus prevent disruption of post-operation wound and formation of urinary fistulae of urethra.
